What Should We Be Doing?Natural disasters occur on Earth every day. They range from earthquake that can’t be felt to Tsunamis that kill and destroy millions of dollars of property. No matter big or small they happen and the best geologist can predict them to a certain degree yet no natural occurring disaster can be entirely predicted or stopped. People seem to look to blame something or someone for these things but we are only able to do so much to lessen the consequences of these disasters.

Mount Vesuvius erupted in 79 A.D. It killed 16,000 people and preserved the city of Pompeii by completely covering it in a pyroclastic cloud of searing hot ash and rock. The cloud moved at speeds of 100-650 MPH at temperatures that ranged from 100 Celsius to 1200 Celsius. These people had zero knowledge of any of the dangers they were putting themselves in on a daily basis. They were not living on the age or thought it was cool to live by a giant destructive volcano. They were simply unaware of the danger because there was no knowledge of it. These people cannot be blamed for this horrific disaster they were caught up in. And in that day in age nobody was aware of the danger. For the people of Pompeii there was no way to lessen the consequences of their disaster because they had no knowledge of the possibility of the disaster itself.

The Sumatra earthquake disaster was extremely devastating. It claimed 286,000 lives and caused irreversible damage to the landscape. It recorded a 9.0 on the Richter scale and induced megathrust, with a vertical displacement of between 30ft and 50ft and 75 miles long(Iris). It lasted for eight minutes and without warning systems the victims of these disasters didn’t have a chance. In this case money was a huge reason why the death total was so big. Without enough funds to provide the city of Indonesia with the proper early warning system countless lives were lost....

...INTRODUCTION
A naturaldisaster is a major adverse event resulting from natural processes of the Earth; examples include floods, severe weather,volcanic eruptions, earthquakes, and other geologic processes. A naturaldisaster can cause loss of life or property damage, and typically leaves some economic damage in its wake, the severity of which depends on the affected population's resilience, or ability to recover.[1]
An adverse event will not rise to the level of a disaster if it occurs in an area without vulnerable population.[2][3][4] In a vulnerable area, however, such as San Francisco, an earthquake can have disastrous consequences and leave lasting damage, requiring years to repair
Various disasters:
Hydrological disasters
[edit]Floods
A flood is an overflow of an expanse of water that submerges land.[8] The EU Floods directive defines a flood as a temporary covering by water of land not normally covered by water.[9] In the sense of "flowing water", the word may also be applied to the inflow of the tide. Flooding may result from the volume of water within a body of water, such as a river or lake, which overflows or breaks levees, with the result that some of the water escapes its usual boundaries.[10] While the size of a lake or other body of water will vary with seasonal changes in precipitation and snow melt, it is not a...

...A naturaldisaster is the effect of a natural hazard (e.g., flood, tornado, hurricane, volcanic eruption, earthquake, heatwave, or landslide). It leads to financial, environmental or human losses. The resulting loss depends on the vulnerability of the affected population to resist the hazard, also called their resilience. if these disasters continues it would be a great danger for the earth.[1] This understanding is concentrated in the formulation: "disasters occur when hazards meet vulnerability."[2] Thus a natural hazard will not result in a naturaldisaster in areas without vulnerability, e.g. strong earthquakes in uninhabited areas.[3] The term natural has consequently been disputed because the events simply are not hazards or disasters without human involvement.[4] A concrete example of the division between a natural hazard and a naturaldisaster is that the 1906 San Francisco earthquake was a disaster, whereas earthquakes are a hazard. This article gives an introduction to notable naturaldisasters, refer to the list of naturaldisasters for a comprehensive listing.
An earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves. At the Earth's surface, earthquakes manifest...

...NATURALDISASTERS
A naturaldisaster is a major adverse event, which can cause loss of life or property damage, and typically leaves some economic damage. There are many types of naturaldisasters: avalanches, earthquakes, volcanic eruptions, floods, tsunamis, blizzards, droughts, hailstorms, tornadoes, wildfires. If an adverse event occurs in an area without vulnerable population, it will not have such disastrous consequences, as if it occurs in area of vulnerable population as in San Francisco.
One of the biggest naturaldisasters, which appear mostly in mountainous area, is avalanche. An avalanche occurs when a mass of snow falls down from the mountainside. That is because new snow, which is not wet, falls on a more heavy snow layer. This causes that the layer of snow is too big and it start to slide down toward the base of mountain. One of the biggest avalanches in world history was in Italian - Austrian Alps. During World War II, Italy and Austria had military bases in the Alps – soon finding that bombs and enemy fire weren't the only threats. Heavy snow instigated a series of avalanches in the Tyrol region causing the deaths of 10,000 soldiers on what became known as White Friday 1916.
Of course one of the naturaldisasters is an earthquake (also known as a quake, tremor or temblor). Earthquake is the result of a sudden...

Introduction
NaturalDisasters is meant bynatural event such as a flood, earthquake, or hurricane that causes great damage or loss of life.
Naturaldisasters happen all over the world and they can be utterly devastating for people’s lives and the environments in which they live. Although naturaldisasters are caused by nature and there is nothing that we can do to prevent them happening, there are many different natural causes that lead to naturaldisasters, and being aware of these causes enables us to be better prepared when such disasters do arrive.
Different Types of NaturalDisasters
One common naturaldisaster is flooding, which occurs when a river bursts its banks and the water spills out onto the floodplain. This is far more likely to happen when there is a great deal of heavy rain, so during very wet periods, flood warnings are often put in place....

...encapsulates as much horror, misery, helplessness and doom as the term “NaturalDisaster”. A naturaldisaster is any event of force of nature that is caused by environmental factors that has catastrophic consequences. Every year they not only decimate thousands of people and their properties but end entire blood lines. These calamities wreak havoc in the part of the world it chooses to act upon.
Over the centuries various types ofnaturaldisasters or “Acts of god” have stolen human lives. Several criterions such as damage, loss of lives or the amount of money that it takes to rebuild are usually used to rank these incidents. However the following ten naturaldisasters have been selected as the most common naturaldisasters around the world on the basis of the global frequency of occurrence. Statistics from the International Strategy for Disaster Reduction (ISDR), an organization headed by the United Nations secretary for humanitarian affairs has been used in this article for rating the various naturaldisasters. The statistics cover the years from 1970-2005.

As Wikipedia defines; the term “infestation” refers to parasitic diseases caused by animals such as arthropods (i.e. mites and ticks), lice, and worms but excluding those caused by protozoa, fungi,...

...NATURALDISASTER:
A naturaldisaster is a major adverse event resulting from natural processes of the Earth. A naturaldisaster can cause loss of life or property damage, and typically leaves some economic damage in its wake, the severity of which depends on the affected population's resilience, or ability to recover.
TYPES OF NATURALDISASTERS:
1-EARTHQUAKES:
An earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves. At the Earth's surface, earthquakes manifest themselves by vibration, shaking and sometimes displacement of the ground.
2-VOLCANIC ERUPTIONS:
The effects include the volcanic eruption itself that may cause harm following the explosion of the volcano or the fall of rock. Second, lava may be produced during the eruption of a volcano.. Third, volcanic ash may form a cloud, and settle thickly in nearby locations.
3-FLOODS:
A flood is an overflow of an expanse of water that submerges land. It causes great damage to buildings, wildlife and humans.
4-LIMNIC ERUPTIONS:
A limnic eruption occurs when a gas, usually CO2, suddenly erupts from deep lake water, posing the threat of suffocating wildlife, livestock and humans. Such an eruption may also cause tsunamis in the lake as the rising gas displaces water.
5-TSUNAMI:
Tsunamis can be caused by undersea earthquake....

NaturalDisasters: Why Haven’t We Learned From Them Yet?
George Santayan, a famous Spanish-American philosopher, once said, “Everything is life is lyrical in its ideal essence, tragic in its fate and comic in its existence,” (“Quotable Quote” 1). This too can be said about naturaldisasters in today’s time. A naturaldisaster is defined in Webster’s Dictionary as, “any form of nature that has catastrophic consequence, such as an avalanche, earthquake, flood, forest fire, hurricane, lighting, tornado, tsunami or volcanic eruption.” Many times the people affected by such an event take a backseat to the actually disaster itself. Why is that? Why is it that certain parts of the world, when hit by a naturaldisaster, seem to be more devastated by it than the same event somewhere else? And, why have those areas at the highest risk of being affected by a naturaldisaster made little to no effort of better preparing themselves for such an event? The disaster part of a naturaldisaster can be prevented when the appropriate steps to better prepare a vulnerable area are taken. By taking the mistakes of the past and learning from them, one has the capability of lowering the statistics of those whom are devastated by a natural...
